Product details

Overview

The LV432776 is a Schneider ComPact NSX400N molded case circuit breaker rated 320 A with an 85 kA ICu breaking capacity at 415 V AC, carrying a MicroLogic 2.3 M electronic trip unit for motor protection. Three-pole fixed-mount design, 690 V AC rated, EN/IEC 60947 compliant, with a toggle control and Class II insulation.

Compared to the single-pole LV438690 (160 A, 250 V), the LV432776 delivers 3 poles, 320 A switching current, 690 V supply voltage, and 85 kA ICu — a step up in both current and voltage class for three-phase motor circuits.

The LV432776 is in active production; lead time is confirmed via RFQ for the exact build code.
